Idref() |
| Modifier and Type | Method and Description |
|---|---|
PathMap.PathMapNodeSet |
addToPathMap(PathMap pathMap,
PathMap.PathMapNodeSet pathMapNodeSet)
Add a representation of a doc() call or similar function to a PathMap.
|
Sequence |
call(XPathContext context,
Sequence[] arguments)
Evaluate the expression
|
void |
checkArguments(ExpressionVisitor visitor)
Method called during static type checking
|
int |
computeSpecialProperties()
Get the static properties of this expression (other than its type).
|
Expression |
copy()
Copy an expression.
|
static SequenceIterator<NodeInfo> |
getIdrefMultiple(DocumentInfo doc,
SequenceIterator keys,
XPathContext context)
Get the result when multiple idref values are supplied.
|
SequenceIterator<NodeInfo> |
iterate(XPathContext context)
Enumerate the results of the expression
|
Expression |
preEvaluate(ExpressionVisitor visitor)
preEvaluate: this method suppresses compile-time evaluation by doing nothing
|
Expression |
simplify(ExpressionVisitor visitor)
Simplify: add a second implicit argument, the context document
|
Expression |
typeCheck(ExpressionVisitor visitor,
ExpressionVisitor.ContextItemType contextItemType)
Type-check the expression.
